CAR-COUPLING.

SPECIFICATION forming part of Letters Patent No. 337,449, dated March 9, 1886.

Application filed July 27, 1885. Serial No. 172,728.

To all whom it may concern:

Be it known that I, JOHN SHANK, of Las Vegas, in the county of San Miguel and Territory of New Mexico, have invented a new and useful Improvement in Oar-Couplers, which improvement is fully set forth in the following specification and accompanying drawings, in which- Figures 1 and 2 are sectional views of a pair of car-couplers, showing my improve ment thereon; and Fig. 3 a perspective view of the same.

This invention relates to an improvement in car-couplers, consisting of an ordinary drawbar provided at its upper forward part with a pin-box and forwardly a projecting piece so disposed as to hold the link, and within the opening of the draw-bar a tongue having a suitable spring, so that the link may be held in a horizontal position while in the act of coupling, all of which will now be fully set forth in detail.

In the accompanying drawings, A represents an ordinary draw-bar provided at its upper forward part with an upwardly-projecting pin-box, B, of any suitable length.

Extending forward from the central opening, 0, of the pin-box, to receive therein the ordinary coupling-pin, D, an opening, E, is provided immediately over the connection of the said pin-box with the upper face of the draw-bar. IVithin this opening E, I provide a forwardly-projecting slide, F, having its forward end, G, upturned, forming a lug, or a kind of a bumper. When this slide F is drawn out, as shown in Fig. 2, the pin D rests upon its rearward end, while immediately forward of the part upon which the said pin D rests is an opening, H, so that when the said slide is pushed rearwardly, as shown in Fig. 1, the pin D will drop through this said opening. Within the usual opening, I, of the draw-bar I provide an upwardly-projecting tongue, J, secured rearwardly within the said opening. This tongue is provided with an opening, K, immediately beneath the pin-box B, so that the pin D may pass through, but not interfere therewith. The forward end of this tongue J is upturned, as shown at L, so that when in use it will rest within the slight recess in the upper wall of the opening I. A spring, N, is placed rearwardly within the opening 1, upon the upper side of the tongue J, so that the (No model.)

normal position of the spring will be nearly horizontal,with the forward end pressing down upon the one end of the link 0 sufficient to hold this said link nearly horizontal.

The opposite draw-bar, as shown in Fig. 2, has its sliding piece F upheld out, with the pin D resting uponits rear end. Then, as the draw-bars approach each other, as soon as the link 0 enters the drawbar the bumper G of the sliding piece F, striking the opposite drawbar, releases the pin D, when it drops down into the draw-bar and secures the link 0 in position.

What I claim as new is 1. In a car-coupler, the central opening projected rearwardly to receive the forwardlyprojecting tongue secured therein, its upper face provided with a spring so disposed as to press the forward end of the tongue downwardly to hold the link in a horizontal position while in the act of coupling, substantially as herein set forth.

2. The combination of the draw-bar provided with a vertical pin box or house hav ing underneath a recess to receive therein a forwardly-projecting slide, so as to hold up the pin, and with its forward end projecting to come in contact with the opposite drawbar, thus forcing it rearwardly and permitting the pin to drop through the opening in the side, so as to engage with the link, with the central opening projected rearwardly to receive the forwardly-projecting tongue secured therein, its upper face provided with a spring so disposed as to press the forward end of the tongue downwardly to hold the link in a horizontal position while in the act of coupling, substantially as herein set forth.

3. The combination of the pin-box B, in connection with the slide E, the pin 0, the forwardly-projecting tongue J, provided at its forward end with an upturned part, L, the spring N, and the link 0, the whole arranged as and for the purpose substantially as herein set forth.

In testimony that I claim the foregoing I have hereunto set my hand, this 2d day of July, 1885, in the presence of witnesses.
